no spark after engine swap

[dancn]

Hi all,

Just been told about this site, looks great.

 

my 1st post, and newbie needs some info::-\............

 

I need some information (schematics) on the old distributor + coil ignition system from the early '90s legacy EJ18.

I recently fitted a 1990 Legacy N/A (carb) EJ18 engine into a project car.

 

The project car does not have a suitable wire loom for this engine, so I'm making a temporary loom to make the engine run.

 

I have fuel but no spark; the engine ran before I removed it from the Legacy.

 

I followed the wires before I removed the engine,

 

there are 2 wires to the coil, one a yellow, ( 12V+ supply, I think) which also feeds to the the distributer, then to a capacitor. The other coil wire is black/blue+red which also goes to the distributor, (changes to black/white at connector)

the black/blue wire comes (as does the yellow) through the bulkhead from the inside of the car.

 

 

 

 

I want to figure out where this black/blue+red wire connects inside the car. (Before removal, I cut this wire just outside the bulkhead, with the engine running, and it didn’t stop!, so I assumed I would NOT need it, I thought it was just for tacho)

I have the yellow conencted to +12v, yet I don't have a spark at the plugs, but it did with the black/blue+red wire cut??

 

This is confusing me some, If I had a schematic I could maybe figure this out

 

This ignition circuit is probably found on other models form late '80s, early '90s

Basically I have +12v to the dis and coil, but the other wire common to both dis and coil is not connected, should it be grounded?

 

 

 

Thanks for any help.

It's for the overseas 92 legacy. We didn't get the 1.8 distributor engine for the Legacy here in the states.
